I guess the most common reason for a wetsuits to get binned is that the seams have gone. How do you find and and repair these and how can you tell if a your wetsuit is repairable or if it has gone too far?
If seams are leaking, gluing and/or retaping the leaking seams will not stop water getting through, as it is the bond between the panels that has opened up. To properly repair leaking seam requires the seams to be trimmed and rebuilt or panels (i.e the crutch panel) to be replaced. We can watertest wetsuits, using a pressurized air line, and as long as a wetsuit is not extensively leaking, then repairing can be very cost effective.
Is the standard inflation test a good way of surfers seeing where your seams have gone?
Liquid welded seams and blindstitched seams can both leak. Our pressure test is very accurate at finding leaks, but surfers can generally tell when a wetsuit is leaking and whereabouts, especially in winter/colder water, as they will feel a cold trickle when sitting on their boards, or when first wading out.
I know every suit is different, but are the any standard costs for seam repair, or knee replacement?
Wetsuit repairs cost from under £10 (so cheaper than buying a tube of neoprene glue). Crutch and knee pad replacements cost from £30. So repairing a wetsuit so that it lasts another season or so it can be used as a back up suit, is very affordable and cost effective.
